How does d con kill mice?

DCon products contain different active ingredients. Their anticoagulant bait products cause death by interfering, upon ingestion, with the production of clotting factors in the blood. After a sufficient dose of the product, the mouse begins to bleed internally and later, external blood loss may be in evidence. This requires 4 to 10 days after ingesting a lethal dose, an advantage because the rodent does not associate symptoms with eating the bait and so there is no bait shyness developed. All anticoagulant products act in the same way, the only difference being the lethal dose required. All these products have an antidote, vitamin K, in the case of accidental poisoning. Tests have shown that anticoagulants are humane, causing the animal to gradually have a loss of energy before death and without the suddent more dramatic symptoms caused by other types of rodent baits. Older versions of anticoagulants showed some genetic resistance develop. The newer anticoagulants do not have a problem controlling rodents.
